高频彩超及X线钼靶检查对乳腺原位癌早期诊断价值的对照分析

Control study between high frequency color Doppler ultrasound and X-ray mammography examination in the early diagnosis of breast carcinoma in situ

目的:探讨高频彩超及X线钼靶检查诊断乳腺原位癌的影像学特点。方法:回顾性分析我院2007年1月—2013年12月经手术证实为乳腺原位癌共30例患者的高频彩超及X线钼靶检查的影像学资料,并作对照分析研究。结果:30例乳腺原位癌患者中,乳腺X线钼靶检查有乳腺癌征象共有21例,诊断正确率70%;乳腺高频彩超检查呈乳腺癌表现的有16例,诊断正确率53%。X线钼靶对乳腺原位癌的诊断正确率(70%)显著高于彩超(53%)。X线钼靶对肿瘤微钙化的正确识别率(66.7%)显著高于彩超(40%)。结论:对于乳腺原位癌的早期影像学诊断来说,乳腺X线钼靶优于高频彩超检查,但二者能取长补短,联合应用两种影像学方法能进一步提高乳腺原位癌的检出率,减少漏诊的发生。

Objective： To investigate the imaging characteristics of high-frequency color Doppler ultrasound and X-ray mammography examination in diagnosing breast carcinoma in situ. Methods： Imaging data of 30 patients with breast carcinoma in situ by comfirmation of pathology were retrospectively reviewed. Both high-frequency color Doppler ultrasound and X-ray mammography examination were between January 2007 and December 2013. Results： Among all 30 patients with breast carci- noma in situ, 21 cases were detected by X-ray mammography examination with a diagnostic accuracy of 70%. 16 cases were detected by high-frequency color Doppler ultrasound with a dagnostic accuracy of 53%. The diagnostic accuracy of X-ray mammography examination （70%） is significantly higher than that of high-frequency color Doppler ultrasound （53%） for breast carcinoma in situ. X-ray mammography examination showed significantly higher rate （66.7%） of tumor microcalcifieation onset than high-frequency color Doppler ultrasound （40%）. Conclusions： For the early diagnosis of breast carcinoma in situ, X-ray mammography examination was better than high-frequency color Doppler ultrasound, but both methods can make complements to each other. A combination of two imaging methods can improve the detection rate of breast carcinoma in situ and further reduce the misdiagnosis rate.
